COMBINED TROLLEY WIRE lAND GUARD HANGER.

Application ledpllay 6, 1924. Serial No. 711,512.

To all lwha-m it may concern.'

Be it known that I, ANTHoNY SHAGI- lKosKI, a citizen of the UnitedStates, residing at Homer City, in the county of Indiana and State ofPennsylvania, have invented certain new and useful Improvements inCombined Trolley Vire and Guard Hangers, of which the following is aspecilication. My ,invention relates to improvementsin hangers, and moreparticularly to a combined trolley wire and guard hanger especiallydesigned for use in coal mines.

In practice, the trolley wire hangers now lso generally employed in coalmines are in many instances secured directly to the coal orrock,constituting the roof of an opening,

and under my invention I also secure the hangers to the roof.

It is required by mining laws, that the trolley wire be protectedespecially at crossovers to prevent operators from coming in contacttherewith, andthis protection has been attempted to be accomplished bythe employment of guard boards disposed on both sides of the wire, andprojecting below the plane in which the wire is located,

which boardsl are held in place by means of .independent wooden plugs,and brackets fixed over the insulators. However, considerable troublehas arisen from the use of the guard boards, due to the inability tokeep them in the desired position, inability Y to prevent mine fires dueto the metal brackets coming in contact with the wire and grounding theroof, also endangering operators ofv coming in contact with the char edbracket. Again if the insulator should iecome grounded due to defect,then the bracket: around the board would become charged, and this wouldcreate a dangerous condition. The diiculty in clamps, after they comeout ati-places where guard boards are employed, and are held in place bymeans of brackets. The

expense, dangerous conditions and diliiculty of putting up or placingguard boards are encountered.

The prime objects of the present invention are to provide a simple andeliicient means for supporting securely and safel these guards,-and atSametime to lessent e diii- .cu1ty, labor, dangerous conditionsto proerty and life, and expense of placing t e guards in positionyandtorovidea new and improved combined tro ley wire and guard hangerconstruction.

Fig. 1 is a transversesectional view embodying my invention.

Fig. 2 is an enlarged section of the bracket and head.

Fig. 3 is a prospective view of a guard supporter, showing how easily itwould be to remove obstruction when working on wire.

Fig. 4 is a plan view of the bracket or ig. 5 is a sectional view of theinsulated connection of the guard supporter and bracket hook.

Fig. 6 is a side elevation of the insulated connection of the' guardhook, this is what insulates the guard vsupporter from the bracket orinsulator.

Referrin tothe drawings, 1 designates the roof of' an opening in a coalmine, the openingybeing designated to permit the passage of electricallypropelled vehicles; 2 the trolley wire, and 3 the anchor structure ofthe hanger may be of any desired construction capable of being securelyattachedto the roof 1. As illustrated, it includes an outer hollow splitcasing or sleeve 4, an interiorly disposed wedge shaped nut 5, said nuthaving its central bore threaded, and an exteriorly threaded rod or bolt6. The

threads of bolt 6 are adapted to engage with u the threads of the nut 5:for the purpose of adjusting said nut within the split hollow sleeve asdesired.

As shown the anchor structure is designedto be positioned within a're-formed hole in the coal roof. Detachab y secured to Ythe lower endof the bolt 6 of the anchor structure is a head 7 8 designates a clampdevice adapted to engage the trolley wire 2, said' 4clamp beingconnected with the head 7 by means of the threaded member 9. The top "ofthe threaded member is of an oval shape 12 is a brace integral with thehea 7, and

this brace helps to su port the top ofthe head'7 at the ends o which arethreaded bores 13 for the reception of the threaded end hook. 14, whichholds the guard in position by means of a pointed set screw 16, which`works within the'threaded bore 17. 18 is the threads of the bore inhead 7. These threads correspond with the threads on bolt 6. Thethreaded bore 18 has a reservoir or space 19 for cotton saturated withoil, which when the 6 turning 'into the threaded bore 18 compresses thecotton saturated with oil and forces oil out of the saturated cotton inreservoir 19 up along the4 groove 20 cut through the threads in the bore18, this process oils the :threads and preserves them from rust.

Into the threaded bores 13 is screwed in or turned in, an insulatingblock 21. The threaded metallic surface 21 is insulated from the innerthreaded core 25 by means of the insulation 24. The threads 22 of themetallic core 25 are ymade for the receptionv y oblong end of the ovalhead 28 is over the short diameter of the oval opening 29. This makestheinsulator block more substantial.

. From the above, it will be apparent, that I have provided a simple andefiicient structure for supporting the trolley wire and the guards andthat the assembled structure may be positioned as a unit, and when notassembledit may be onlyI used Jfor the wire, where the ards are, notnecessary, but when guarda1` are required it is all assembled as a unit,therebyeliminating the employment of separate means for supporting thewire and the guards. Further, that the guardswill always be maintainedin the desired positions relative to the wire. The insulator o alonewill not rust to the anchor structure and there by when wire is takendown, the insulators will be easy to disconnect from the anchorstructure, due to the automatic oiling system. The dangers of the minefires due to guard board bracket grounds is over come by the insulatingblock orconnection between the guard hook and the `main insulator.

What I claim is: 1. In a combined trolley wire and guar hanger, thecombination with an anchor structure, of means carried by the anchor forsupporting a trolley wire guard, said latter supporting means includinga bracket having spaced apart two threaded bores for the reception ofthe insulator block or connection, said insulator connection having avthreaded bore in the center, which is insulated from the outside, aguard supporting hook having a threaded upper end adapted to be threadedinto said center bore, and a set screw adapted to secure the guard tothe said hook.

2. A trolley hanger for mines comprising a bracket embodying oppositelyprojecting guard hooks, which are insulated from the bracket by ymeansof insulator blocks, an insulator head, the insulator head being lformedwith a downwardly projecting stud bolt whose oval head is fitted intooval socket of insulator head, the upper face of the bracket above theinsulator head, being formed with a downwardly projecting screw threadedsocket, having an oil packing reservoir at'bottom, small trench leadingfrom reservoir up across the threads, thev outer ends of bracket beingformed with threaded v bores for the reception of insulator blocks,

and these blocks in turn to receive the threaded ends of the guardhooks, which support the guards in their position- .byl

means of set screws. y j j ANTHONY SHACIKOSKI..
